FIG. 2 shows the recording layer (the recording film L0 layer and the recording film L1 layer) of the optical disc 1. The recording layer of the optical disc is spiral, and a wobbling groove (snake track) is formed at a fixed frequency. Therefore, in the optical disc 1, the magnetic tracks are formed by grooves and the magnetic tracks are formed alternately every one cycle by the parting surface. The meandering track is detected based on a PP (push pull) signal, and is used to generate a synchronization signal. The 1-round magnetic track of the optical disc 1 is composed of 8 segments.

The number (period) of meandering tracks formed as tracks belonging to the same section is common. That is, the zigzag orbits of (420 + 6i) period are formed by the segments inside the zone Zi at the i (i = 0, 1, ...). Therefore, a serpentine track with a period of 8 (420 + 6i) is formed on the magnetic track belonging to the zone Zi. For example, the section 'Z' in the innermost zone (i = 0) is formed with the paper size applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -10- 584847 A 7 B7 V.

Also, for example, a segment of the second (i = 2) outermost zone Z2 is formed with a serpentine orbit of 432 (= 420 + 6 x 2) cycles. Therefore, a serpentine track having a period of 345 6 (= 8 (420 + 6 X 2)) is formed on the track 'belonging to the zone Z2. The serpentine track of the magnetic track formed on the innermost periphery of each zone is formed. The wavelength is common. The address recorded in the title area is 'radiated in the form of CAV (Constant Angular Velocity)' in each section. The innermost peripheral density of each section is common. Figure 3 Series It is displayed in the title area of the segment, and is composed of 1080ch information recorded by embossed bits or symbols. The segment symbol SM1 of 60ch is a unit model with a title displayed. VF01 of 414ch is a continuous phase introduced by PLL (Phase Locked Loop) Data model. The angle PrAl set before 30ch is a model for automatic zoom control and offset control. The address mark AM1 of 21ch is a model showing the address before ID1. The address ID1 of 102ch is a track address. Segment address, and CRC (Cyclic Redundancy Check) code. Set the angle PoAl after 6ch, which is a model that uses address ID1 to meet the rules of channel coding. VF02 of 8 8ch is a continuous data model introduced by PLL. Set before 30ch Angle PrA2 It is a model for automatic enlargement control and offset control. The address mark AM2 of 21ch is a model showing the address before ID2. The address ID2 of 102ch is a track address, a segment address, and a CRC (Cyclic Redundancy Check) Code. The angle PoA2 is set after 6ch, which is the model for address ID2 to meet the rules of channel coding.

Description of the invention (13) The sequence engine 13 performs a snake track enable signal and outputs it to the phase comparator 24. The phase comparator 24 displays the phase difference of the PLL input signal input by the gate and the PLL reference signal input of the perimeter 27 to generate a phase difference signal and outputs it to the low-pass filter (LPF) 25. The low-pass filter 25 is used to remove the high-frequency component of the phase difference signal and output it to VC0 (Voltage Controlled Oscillator) 26. VCO26 is to make the voltage of the phase difference signal 0, which is used to adjust the frequency and phase and to oscillate the clock signal. The cycler 27 is a clock signal that oscillates the VC026 in cycles, and outputs the obtained PLL reference signal to the phase comparator 24. FIG. 8 shows a first configuration example of the header area detection circuit 14. In the first configuration example, the snake track formed on the magnetic track is used to detect the title area by inverting its period two cycles before the title area. The band pass filter 21 is used by the optical header circuit 8 to extract only the serpentine orbit frequency component of the input PP signal, and outputs the serpentine orbit signal that can be displayed in the first stage of FIG. 9 to the comparator 32. Instead, a high-pass filter may be used instead of the band-pass filter 21. The comparator 32 converts the meandering signal to a predetermined threshold value, and converts 0 and 1 shown in the second paragraph of FIG. 9 into 2 signals that appear alternately and outputs the signals to the model detection unit 34. The cycle divider 33 is used by the meandering circuit 12 to input the channel clock signal in cycles, and outputs the meandering clock signal shown in the third stage of FIG. 9 to the model detection output section 34. The model detection output section 34 is synchronized to the meandering clock signal by the cycle divider 3 3 and is used by the comparator 3 2 to monitor 2 The paper size applies the Chinese National Standard (CNS) A4 specification (210X29?

The data symbol to which the pointer is attached is to correct the pointer ledger by the main correction symbol LCD (Long Distance Code) (248, 216, 33) shown in FIG. Next, the data recording processing of the unformatted optical disc 1 by the optical disc drive to which the present invention is applied will be described with reference to the flowchart of FIG. However, the optical disc drive 1 to which the present invention is applied has not been subjected to formatting processing, as shown in FIG. 15A. In the manufacturing process, the header area of the recording film L1 layer is made by the concave and convex bits. Parting surface titles and groove titles are recorded. That is, the recording film L0 layer of the optical disc 1 is not formatted, but the recording film L1 layer is formatted. In step S1, the optical disc drive is used to detect the title area of the recording film L0 layer of the optical disc 1. As shown in FIG. 16, a mark is used to record the groove title on its groove, and a mark is used on its parting surface. Used to record the parting surface title. Specifically, the title area detection circuit 14 detects the title area of the recording film L0 layer based on the PP signal inputted from the optical title circuit 8 and the channel clock signal inputted from the meandering circuit 12 and uses this information. The output to the address encoder 15 is used to generate and encode an address, and output the obtained title signal to the recording and reproduction circuit 9. Further, the recording / reproducing circuit 9 is provided to supply the title signal to the optical title circuit 8, and the optical title circuit 8 is used to control the laser output of the optical pickup 7 corresponding to the title signal. The optical pickup 7 is based on the optical The header circuit 8 is controlled to irradiate laser light so that a groove title is recorded in a groove in the title area of the recording film L0 layer, and a parting surface title is recorded on the parting plane. This standard is applicable to China National Standard (CNS) A4 specification (210X297 mm). -18- -------- f, (Please read the notes on the back before filling this page) Printed by the Bureau ’s consumer cooperative 584847 A7 _ _ B7_ V. Description of the invention (16) By the process of step S1, as shown in FIG. 15B, the title is recorded in the title area of the recording film L0 layer to complete the formatting by marking. Thereafter, in step S2, the optical disc is driven, and among the recording film L0 layer and the recording film L1 layer of the optical disc 1, the recording film L0 layer is first used to start the formation of the marks corresponding to the recorded data. Specifically, the AV recorder 3 uses the AV interface to input the recorded data, and the error correction circuit 11 is used to add an error correction symbol, and the demodulation and demodulation circuit 10 is modulated into a 2-frame signal, so that recording and reproduction are performed The circuit 9 performs recording compensation. According to the control of the optical header circuit 8, the optical pickup 7 is used to irradiate laser light, so that a mark corresponding to the recorded data is formed on the recording film L0 layer. Thereafter, as shown in FIG. 15, after the recording film L0 layer is cut off (after all data areas of the recording film L0 layer are used to record marks), in step S3, the optical disc drive is performed as shown in FIG. 15D during recording. The film L1 layer is used to form marks corresponding to recorded data. Yes, the method for forming marks in the data area is the recording of the parting surface groove as shown in Figure 17, the method of forming on both the parting surface and the groove, and the groove recording as shown in Figure 18, There are two methods of forming only one of the parting surface and the groove. As described above, if the optical disc drive according to the present invention is applied, when the recording film L1 layer is used to form a mark, the entire title area and data area of the recording film L0 layer have been formed with marks, and Since the concave-convex bit system is not formed in the recording film L0 layer, the transmittance of the recording film L0 layer is the same.

If there is "the recording film L0 layer is once formed into the formatted optical disc 1, once again" when it is used to record data, it is only necessary to perform the processing after step s2. Also, "the process of step S1 for formatting the layer L0 of the recording film is performed continuously". All the data areas of the layer L0 of the recording film can be used to record false marks. If the optical disc drive according to the present invention is applied, then The serpentine track formed on disc 1 can be used to generate a channel clock signal by adding PLL to the frequency, so that the entire disc drive can be operated with high accuracy. Furthermore, if the optical disc drive according to the present invention is applied, a high-precision synchronization signal is obtained according to the meandering track, so that, for example, the thickness of the cover layer is formed to a thickness of about 0.1 mm, and the influence of dust and the like on the surface will change. Big 'uses bumps and marks as a read loss, but can be easily used to perform error correction. However, if the format of the optical disc 1 is sold for the purpose of selling, it is in the title area of the recording film layer L0 of the optical disc 1 by using a mark to record only the title as a device. When the optical disc drive is used, it is shown in FIG. 6 The configuration example shown can be used to eliminate the AV interface 3, the variable demodulation circuit 10, and the error correction circuit 11.
